Volume widget

Simple and easy-to-install widget for Awesome Window Manager which shows the sound level:

Note that widget uses the Arc icon theme, so it should be installed first under /usr/share/icons/Arc/ folder.

Customization

It is possible to customize widget by providing a table with all or some of the following config parameters:

Name	Default	Description
volume_audio_controller	pulse	audio device

Installation

• clone/copy volume.lua file;

• include volume.lua and add volume widget to your wibox in rc.lua:

require("volume")
...
s.mytasklist, -- Middle widget
	{ -- Right widgets
    	layout = wibox.layout.fixed.horizontal,
		...
		volume_widget(),
		...      

• Optional step. In Arc icon theme the muted audio level icon () looks like 0 level icon, which could be a bit misleading. So I decided to use original muted icon for low audio level, and the same icon, but colored in red for muted audio level. Fortunately icons are in svg format, so you can easily recolor them with sed, so it would look like this ():

cd /usr/share/icons/Arc/status/symbolic && 
sudo cp audio-volume-muted-symbolic.svg audio-volume-muted-symbolic_red.svg && 
sudo sed -i 's/bebebe/ed4737/g' ./audio-volume-muted-symbolic_red.svg 

Pulse or ALSA only

Try running this command:

amixer -D pulse sget Master

If that prints something like this, then the default setting of 'pulse' is probably fine:

Simple mixer control 'Master',0
  Capabilities: pvolume pvolume-joined pswitch pswitch-joined
  Playback channels: Mono
  Limits: Playback 0 - 64
  Mono: Playback 64 [100%] [0.00dB] [on]

If it prints something like this:

$ amixer -D pulse sget Master
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused

amixer: Mixer attach pulse error: Connection refused

then set volume_audio_controller to alsa_only in widget constructor:

volume_widget({
    volume_audio_controller = 'alsa_only'
})

.

Control volume

To mute/unmute click on the widget. To increase/decrease volume scroll up or down when mouse cursor is over the widget.

If you want to control volume level by keyboard shortcuts add following lines in shortcut section of the rc.lua (the commands could be slightly different depending on your PC configuration):

awful.key({ modkey}, "[", function () awful.spawn("amixer -D pulse sset Master 5%+") end, {description = "increase volume", group = "custom"}),
awful.key({ modkey}, "]", function () awful.spawn("amixer -D pulse sset Master 5%-") end, {description = "decrease volume", group = "custom"}),
awful.key({ modkey}, "\", function () awful.spawn("amixer -D pulse set Master +1 toggle") end, {description = "mute volume", group = "custom"}),
